We perform nasal lacrimal duct probing at "K+31" when tears stop draining properly and persistent tearing, inflammation, or recurring discharge occurs. For patients in Moscow, it's important not only to undergo the procedure quickly but also to receive a clear diagnosis, a gentle approach, and post-treatment support. That's why, before the procedure, we always assess the condition of the lacrimal system and explain whether probing is truly necessary or whether a more conservative approach can be used.
At "K+31," we do everything we can to ensure our patients' peace of mind. A diagnostic evaluation is mandatory before surgery. This means we first establish a diagnosis and only then prescribe treatment.
Before probing the nasolacrimal duct, we:
The doctor also checks the patency of the lacrimal ducts and whether there are any contraindications to the procedure.
Lacrimal duct irrigation is performed after the examination.
Lacrimal duct probing itself is performed very quickly. A hospital stay is not required: the doctor immediately evaluates the results and provides recommendations for further monitoring.
| Method | When used | What it does |
|---|---|---|
| Lacrimal sac massage | In the early stages, more often in children | Can help restore drainage |
| Lacrimal duct irrigation | For diagnosis and, in certain cases, treatment | Indicates the level of patency |
| Probing | For persistent obstruction | Helps restore duct patency |
The procedure is generally well-tolerated. We use local anesthesia, so there's usually no significant pain. Our approach may differ for adults and children.
It's important to us that the appointment is calm and stress-free. That's why we explain to the patient and parents in advance how the procedure will proceed and what sensations they may experience afterward.
The causes of tear drainage problems vary among different age groups. Therefore, the treatment is always individualized.
In newborns and young children, the problem is often related to the duct not fully opening after birth. Parents notice constant tears, discharge, or fluid accumulation in the corner of the eye.
At an early stage, a pediatric ophthalmologist may recommend lacrimal sac massage and observation. If there is no effect, probing of the nasolacrimal duct is considered.
For many children, the procedure helps quickly restore normal tear drainage and reduce the risk of chronic inflammation.
In adults, obstruction can develop after inflammation, injury, age-related changes, or chronic nasal diseases.
Sometimes, patients use drops on their own for a long time, but this does not resolve the underlying problem. In such cases, diagnosis and assessment of the entire drainage system are required.
After the procedure, the doctor may prescribe drops, a follow-up examination, and restrictions for several days. It is important to follow all post-procedure recommendations and not discontinue treatment prematurely.
A follow-up examination is also sometimes required to ensure that patency has been fully restored.

What is nasolacrimal duct probing and when is it needed?
Nasolacrimal duct probing is a procedure in which a doctor restores the patency of the tear drainage pathways. Most often, the problem is due to a partially or completely blocked nasolacrimal duct, which causes tears to stagnate and creates conditions for inflammation.
This condition occurs in both adults and children. In some patients, symptoms develop gradually, so many put off seeing a doctor for a long time, believing constant tearing to be a temporary problem.
How the lacrimal drainage system works
Normally, tears constantly moisten the surface of the eye and then drain through the lacrimal puncta into the lacrimal sac, and then into the nasolacrimal ducts. If this system is not functioning properly, the fluid begins to stagnate.
Due to drainage obstruction, the following may occur:
Prolonged congestion increases the risk of developing dacryocystitis—inflammation of the lacrimal sac.
Signs of lacrimal duct obstruction
The main symptom is constant lacrimation, not associated with wind or bright light. Some patients notice that the eye is constantly wet, and discharge appears in the morning.
Other signs that may indicate a problem include:
If symptoms persist, the doctor will evaluate whether the nasolacrimal duct is blocked and how severe the changes are.
When irrigation helps, and when probing is needed
Not all patients require a procedure right away. Sometimes we begin with observation, drops, or conservative treatment. In infants, lacrimal sac massage can be used, which helps restore fluid drainage early on.
Irrigation of the lacrimal duct is also used. It helps assess the patency of the tear ducts and, in some cases, alleviates symptoms.
However, if the problem persists, recurrent inflammation occurs, or persistent obstruction of the nasolacrimal duct develops, the doctor may recommend probing.
